This invention relates to marking machines for making impressions upon leather and other materials to indicate the outlines for the guidance of subsequent operations.

An object of the invention is to provide a machine for the purpose stated comprising a support or the material or articles to be marked, and a manipulative die supporting device movable from a position to receive a marking substance, such as ink, to a position to press upon the material to be marked and make an impression thereon with the marking substance to indicate the outlines for subsequent operations.

Another object of the invention is to provide a marking machine equipped with means 'l for properly locating and holding the materials to be marked, so that the die will make the proper impressions in'proper lo-' 0 cations without the requirement of anyparticular care or attention by the operator after the materials have been located.

Another object of the invention is to'provide an improved marking machine having 2'5 a movable support for the dies, and means for attaching the dies to such support and operating the support and thereby the dies to mark the outlines for subsequent operations upon the materials supported in proper position for that purpose.

Another object of the invention is to provide an improved marking machine having die supporting mechanism, and means facilitating the operation of said mechanism to apply to the dies a proper marking substance and to operate the dies to apply the marking substances to the materials to be marked for subsequent operations.

Another object of the invention is to provide an improved marking device comprising a base member, a member movable relatively thereto and engageable therewith, a guide pattern on said base for receiving the parts to be marked and comprising an element provided with guide elements and re- S.eria1 No. 323,510.

movably secured to said base member, and a marking pattern removably secured to said movable member and provided with marking means. An advantage of this construction `is that the work locating and supporting devices are interchangeable and removable from the machine, and that the marking delvices also are interchangeable and removable,

required to be claimed herein if granted to Other objects will appear from the following description, reference being made to the accompanying drawings, in which Fig. 'l is a front elevation of my improved marking machine.

Fig. 2 is a side elevation.

Fig. 3 is a vertical longitudinal sectional view.

Fig. 4 is a plan view.

Fig. 5 is a detail view of the die clamping device.

Fig. 6 shows a specimen of die marker, although it 'will be understood that various shapes, designs and forms of die markers may be used on this machine.

Iig. 7 is a detail view of the stop for the die loc My improved machine is constructed and arranged to be mounted @ipon any appropriate form of support such as the frame 1 which is of suiiicient height to support the machine at the proper height for convenient operation.

The machine comprises a base which, in the ormshown, includes a die supporting portion 2-at the front and a marking substance supporting portion 3 at the rear. As shown, the means for applying a marking substance to the dies comprises a pan or tray 4 designed and arranged to contain a vquantity of ink and an ink pad 5. The pan 4 may be secured to lthe base by screws 4a. i

The work locating and supporting devices are interchangeable and removable from the machine, so that materials cut to ditlerent shapes and dimensions may be properly located by the use of an appropriate specially designed locating device. Each of such locating devices, one of which is shown, comprises a gage plate 6 having on its upper side forms 7 to receive marginal or projecting portions of the materials to be marked and thus expedite and facilitate proper location of the materials for operation of the marking device. Each of said plates 6 is provided with a number of holes arranged to receive pins 8 extending from the frame supporting part 2 and thus hold the plates 6 immovable in proper location.

vao

The die carrier comprises a frame 9 swingingly supported by a pair of front arms 10, the upper ends of which are pivoted to the lateral ends of the die carrier and the lower ends of which are connected to the base by pivots 11, and a pair of rear arms 12 having -their upper ends pivoted to the die carrier 9 and their lower ends attached to a rock shaft 13 extending across the machine below the pad pan 4. A handle 14 is connected with the die carrier 9 by the stem 15a and die lock or clamp arm 15 passing through the die carrier 9 and anchored in the handle, whereby a turning connection of the handle with the die carrier is obtained. The lock or clamp arm 15 is within a recess 16 in the under side of the die carrier and is operative bythe handle 14 to engage and secure the die plate to the die carrier. The extent of' turning movements of the handle 14 is limited by a disc 14al attached to the handle and provided with a notch 14b in one edge into which a pin 14c extends. The pin 14c is rigid with the die carrier and the notch 14h is of sufhcient length to permit the 4handle 14 and the clamp or lock 15 to `be `turned approximately one-fourthv of a revolution.

The machine is arranged to receive die plates having marking diesof different de.- signs adapted to mark the materials placed on the gage plate for subsequent work or operation. One such die plate 17 is shown and is provided with a pair of spaced projections 18 arranged to extend upwardly into the recess 16 so that the ends of the die.

lock or clamp arm 15 may engage under the projections 18 to secure the die plate to the carrier. Each die plate 17 also has a number of upwardly kprojecting lugs 17 1 arranged to engage in holes in the die carrier to locate the die plates properly and to cooperate with the lock or clamp arm to hold the die plates rigid on the carrier. The edges 19 (Figf5) of the die lock or clamp arm 15 are beveled swing the die carrier successively -rom the ink pad 5 to the pieces of material succes` sively placed on` the gage plate; or, the machine may be operated by a treadle device.

As shown, a number of counterbalance weights 21 are rigid with the shaft 13 in a relationship in which said weights tend to support the die carrier in anintermediate position between the pad 5 and the gage plate for movement in either direction. The treadle connections comprise a treadle cord 22 extending over and attached to a pulley 23 rigid with the shaft 13. The cord 22 mayr be vheld from slipping on the pulley by a clamping device 24 holding the cord 22 in clamped connection with the pulley. The cord 22 crosses below `the pulley 23 and has one end connected to the forward end ofV a treadle 25 by a tensioning device 26, and the opposite end connected to the rear end of the treadle by a tensioning device 27. The tensioning devices are operative to take up the slack in the cord resulting from con-4 tinued use of the machine. Rocking of the treadle in one direction will swing the-die carrier to inking position and in the opposite directionwill swing the die carrier to niarking position. When both the treadle and the handle 14 are released the counterbalance 4weghts 21 raise the die carrier to intermediate position readyy for further operations. It is now clear that the arms 10 and 12 support the die carrier 9 for swinging `movements from and to the inking element 5 and the shoe parts located on the gage device 6, andv that the actuator 14 for the die carrier wholly supported thereby. The carrier 9 1 .is equipped with means 15 and 17a for looperations, and also by producing themarkings in the precise relationship desired.
